Advanced Energy Materials, EarlyView.Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...

Angewandte Chemie, EarlyView.Sialyl glycosides containing 4‐N‐derivatized sialic acids synthesized by a highly efficient one‐pot two‐enzyme (OP2E) chemoenzymatic sialylation strategy have been shown to be versatile probes. They can resist sialidase cleavage, be selective substrates by influenza sialidases, or be nanomolar substrate analog‐based inhibitors and affinity ligands ...

The effect of geographical denomination on the uptake of fungus‐resistant grapes
Applied Economic Perspectives and Policy, EarlyView.Abstract Grape production for wine making is of great economic and cultural importance in Europe, but is heavily dependent on pesticides. Reducing pesticide use and associated risks is a policy goal in several countries, particularly in Europe. The most effective strategy to substantially reduce pesticide use in grape production is the planting of ...

Self‐Photosensitizing Cobalt Complexes for Photocatalytic CO2 Reduction Coupled with CH3OH Oxidation
Angewandte Chemie, EarlyView.Self‐photosensitizing non‐noble metal complexes achieve CO2 photoreduction coupled with CH3OH photooxidation, simultaneously synthesizing formic acid in the absence of any additional photosensitizers and electron sacrificial reductants. Abstract The use of metal complexes as homogeneous molecular catalysts has attracted considerable attention regarding

Advanced Energy and Sustainability Research, EarlyView.Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.

The incompressible Navier-Stokes system with time-dependent Robin-type boundary conditions [PDF]
arXiv, 2014 We show that the incompressible 3D Navier-Stokes system in a C 1;1 bounded domain or a bounded convex domain with a non penetration condition u = 0 at the boundary @ together with a time-dependent Robin boundary condition of the type curl u = (t)u on @ admits a solution with enough regularity provided the initial condition is small enough in an ...

Taxonomy of Chemical Bondings: Opportunities and Challenges
Angewandte Chemie, EarlyView.The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.

Diamagnetism versus Robin condition and concentration of ground states [PDF]
arXiv, 2015 We estimate the ground state energy for the magnetic Laplacian with a Robin condition. In a special asymptotic limit, we find that the magnetic field does not contribute to the two-term expansion of the ground state energy, thereby proving that the Robin condition weakens diamagnetism.

Sensor‐Embedded Muscle for Closed‐Loop Controllable Actuation in Proprioceptive Biohybrid Robots
Advanced Intelligent Systems, EarlyView.Skeletal muscle tissue‐based bioactuators move in response to externally applied electrical stimuli in open‐loop control, which lacks knowledge of the actuator's state. Herein, a soft and fiber‐shaped piezoresistive mechanosensor that integrates with the soft tissue and operates in the cell culture environment is used to create the first proprioceptive
